Why is your car temperature Rising while at an idle and then goes down when you are moving?
When your car is at idle there is no air flow to cool the radiator, but when your car moves the air flow through the radiator cools it down. I would suspect the radiator fan is not coming on when it should. If the fan is working properly the engine temperature should stay fairly constant assuming the thermostat is also working properly.
Does the fluid in the radiator have to flow as soon as you turn the engine on?
No , the engine coolant will start flowing through the radiator when the engine coolant thermostat starts to open ( assuming everything is working properly ) Helpfull
How to check to see if the water pump on the car is working properly?
Not hard. Take the radiator cap off and crank it up and let it run until it gets to operating temp. You should be able to see the coolant moving inside the radiator. if it is, it's working.

remove radiator cap, and watch the fluid, ull know that the water pump and thermostat is working if you see the coolant flowing around, kinda like a small creek in the radiator.

If you have replaced the water pump then flush the radiator with CLR also check to see if the fan is working properly.
Why is your car running hot not for the normal reasons?
Low coolant level? Thermostat not opening? Radiator plugged? Defective radiator cap? Water pump not circulating coolant? System airbound? Collapsed radiator hose? Timing not adjusted properly (too far advanced)? Head gasket? Gauge not working properly? Temperature sending unit?
